The pair are best friends on the E4 reality series and returned with the rest of the Made in Chelsea cast earlier this week, pulling in over 700,000 viewers.
Matthews has promised that it will be the best series yet, telling Digital Spy: "It just gets more and more dramatic. The longer you stay in the show, the more comfortable you get about slagging people off.
"I personally think the storylines that have naturally fallen into place this series are the best so far - people have made some real mistakes and it's been pretty fun filming about it!"
Made in Chelsea continues Mondays on E4 at 10pm. Watch Matthews discuss the show below:
